Opioid Conversion Calculator downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. iPhone downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

About Opioid Conversion Calculator
Opioid Conversion Calculator is built for health professionals who need a clear, efficient way to compare opioid doses and review the clinical context behind a conversion. Built by a pharmacist.
CALCULATE AND COMPARE
- Calculate total oral morphine equivalent (OME) across multiple opioids and routes: oral, parenteral, rectal, sublingual and transdermal.
- See every converted dose at once, after applying a chosen Target OME percentage for incomplete cross-tolerance.
- View conservative, rounded-down target and breakthrough dose suggestions.
- See where a daily dose sits: the header warms from orange at 50 mg/day (CDC 2022) to red at 120 mg/day (Opioids Aware). Adjust the thresholds or turn the guide off.
- Methadone uses its own dose-dependent model, and its results are clearly marked as not a starting dose.
- Convert the same opioid between routes, such as oral and parenteral morphine, with the method and sources shown.
EVERY RESULT, IN CONTEXT
- Each result opens with the converted dose, then products, clinical information, breakthrough dosing and switching timing.
- Read practice points alongside formulation-specific pharmacology, with links to the supporting sources.
- Check when to start the new opioid when switching between patches, modified-release opioids and CSCI. Switching timing is also in the menu, free for everyone.
- View official products and strengths for Australia, the United States, Germany, France and Spain, chosen independently from the app language.
TAILOR THE WORKFLOW
- Edit conversion factors and choose which opioids appear, with Pro.
- Export and import settings when moving between devices, with Pro.
- Works offline, including on first launch.
- Use the app in English, French, German, Italian, Portuguese (Brazil) or Spanish.
PRO ACCESS
The calculator stays free: the combined OME and every converted dose need no account or purchase. Pro adds breakthrough dosing, switching timing, products and clinical information to every result, plus custom conversion factors, opioid visibility and settings transfer. Your first detailed results are free to try. Available plans, prices and any introductory offer are shown using the information supplied by the App Store before purchase. Purchases can be restored in the app.
CLINICAL USE
Equianalgesic conversions are estimates and do not replace clinical judgement. Consider incomplete cross-tolerance, patient factors, formulation, route, local guidance and monitoring when interpreting a result. Review the references and terms of use before using the calculator in clinical practice.

Latest updates
4.0.0
A cleaner, calmer design with the result first, and new tools for switching opioids.
• Dose colour guide. The equivalent header warms from orange at 50 mg/day (CDC 2022) to red at 120 mg/day (Opioids Aware). Move the thresholds or turn it off in Menu › Dose colours, for example for palliative care.
• The result comes first. Each result opens with the converted dose, then products, clinical information, breakthrough dosing and switching timing, with the regimen it came from below.
• Route conversion. Compare daily doses of the same opioid by different routes, such as oral and parenteral morphine, or oral and IV methadone, with the method and sources shown. Find it in the menu.
• Switching timing for everyone. See when to start the new opioid when changing between patches, modified-release opioids and CSCI, straight from the menu.
• Methadone, explained. Methadone results show how they were calculated and are clearly marked as not a starting dose.
• Works offline from the first launch. A built-in medicine list means the calculator works before the app has connected.
• Up-to-date products. Products and strengths are refreshed monthly from official sources, without waiting for an app update.
• Clearer capped doses. When a dose is held at a medicine's maximum, the row says what it was capped from, in one calm line.
• Easier to read at a glance. Your phone's own system font with aligned figures, and doses without trailing zeros, so 40 can't be misread as 400.
• Better on iPad, with a readable column and centred sheets.
• Fewer interruptions. Once you accept a dose above the usual maximum, stepping it with + no longer asks again.
